Supply chain traceability is now part of several product compliance and Digital Product Passport discussions.
Under the ESPR, the Digital Product Passport is expected to make product information available across the value chain and support product traceability. In the textile sector, recent JRC work also shows that future DPP content may rely on information linked to textiles, production, certifications, and product identification.
This raises a practical question: how much traceability information is actually needed?
The answer is not necessarily every supplier, every process, or every available data point. Different regulatory and operational objectives require different information. This guide explains what supply chain traceability means, what information is commonly collected through traceability activities, and how it connects to Digital Product Passport preparation.
Supply chain traceability refers to the ability to identify, access, and connect information about products, materials, suppliers, and production activities across a value chain (United Nations Economic Commission for Europe, 2022).
It can support different objectives, including compliance checks, certification management, sourcing visibility, product information management, reporting, and Digital Product Passport preparation.
Traceability is therefore not one fixed process. Its scope depends on the information that needs to be collected, verified, maintained, or shared.
Traceability is often associated with full supply-chain mapping. In practice, current EU frameworks do not define one universal traceability model that applies to every product and sector.
The ESPR introduces Digital Product Passports through product-specific delegated acts. This means information requirements are defined by product group and regulatory objective.
For this reason, the relevant question is not always how many suppliers should be mapped. It is which information is needed, for which purpose, and at which level of detail.
Traceability activities can involve different types of information depending on the objective.
Supplier information - manufacturers, processors, subcontractors
Material information - fibres, materials, components
Production information - manufacturing locations and production stages
Certification information - product, material, and facility certifications
Product information - product identifiers, composition, specifications
These categories should not be read as a universal mandatory list. They are information areas that commonly appear in traceability, product compliance, and Digital Product Passport preparation work.
Different objectives require different levels of information.
A certification process may require material sourcing information and chain-of-custody documentation. A product compliance requirement may depend on manufacturing information, material composition, or supporting documentation. A Digital Product Passport may require structured product-level information defined by the relevant delegated act.
This means there is rarely one fixed answer to how much traceability is needed.
A more useful starting point is to define the objective first, then identify the information required to support it.
Many information categories being explored for future DPPs rely on data that organisations often obtain through traceability activities. In textiles, JRC work discusses data linked to product identification, producer information, textiles information, certifications, manufacturing information, and compliance documentation.
For many organisations, traceability therefore becomes one of the mechanisms used to gather, verify, and maintain information that may later be published or accessed through a Digital Product Passport.
For many organisations, the first step is not collecting new data but understanding what information already exists across suppliers, products, certifications, and internal records.
Renoon helps organisations assess existing supply-chain information, identify the data needed for compliance and Digital Product Passport requirements, and build a structured approach to traceability.
